Cystic biliary atresia (CBA), a rare cystic expansion of atretic extrahepatic bile ducts in young infants, overlaps in age at presentation and imaging features with early choledochal cysts (CC). Treatment and prognosis differ; histologic differences are unsettled. We compared 10 patients with CBA, 1975 to 2015, to an age-similar cohort of 13 infants, and to older patients who had surgery for CC. Operative details, imaging, and clinical courses were correlated to pathologic specimens. Immunostains for smooth muscle actin and myosin heavy chain were used to evaluate cyst walls and atretic segments...

RATIONALE: Von Hippel-Lindau (VHL) disease is a rare inherited, autosomal-dominant syndrome caused by heterozygous germline mutations in the VHL gene. VHL patients are prone to develop benign and malignant tumors and cysts in multiple organ systems involving kidneys, pancreas and central nervous system (CNS). The varied and complex clinical manifestations and radiological findings of VHL are of interest. PATIENT CONCERNS: We report a 38-year-old woman with a ten-year history of VHL disease involving both pancreas and biliary system...

OBJECTIVE: To identify predictive factors for gastroduodenal bleeding after postoperative radiation therapy in patients with biliary tract cancer. METHODS: We identified 186 patients with biliary tract cancer who completed scheduled postoperative radiation therapy from March 2000 to August 2013. To isolate the effects of radiation on gastroduodenal bleeding, patients with pylorus-preserving pancreaticoduodenectomy, pylorus-resecting pancreaticoduodenectomy or Whipple surgery (n = 67) were excluded from this analysis...

BACKGROUND: Mucin-producing cholangiocarcinoma (MPCC) is an uncommon tumour that is clinically characterized by mucin-hypersecretion. Because the initial symptoms of MPCC may be attributed to the viscus mucobilia, the primary tumour mass may potentially be unrecognizable. We report an interesting case of curatively resected occult MPCC in situ. CASE PRESENTATION: A 70-year-old man was referred to our hospital with increased levels of biliary enzymes. Multidetector row computed tomography (MDCT) demonstrated a diffuse dilatation of the entire biliary system without evidence of tumour mass...

Of all the intra-abdominal solid organs, the liver is the most vulnerable to blunt abdominal trauma. The majority of liver ruptures present in combination with other abdominal or extra-abdominal injuries. Over the last three decades, the management of blunt liver trauma has evolved from obligatory operative to non-operative management in over 90% of cases. Penetrating liver injuries more often require operative intervention and are managed according to adult protocols. The greatest clinical challenge remains the timely identification of the severely damaged liver with immediate and aggressive resuscitation and expedition to laparotomy...

This review highlights the complications and their risk factors encountered in pediatric hepatobiliary surgery, specifically in the context of pediatric hepatic resection, excision of choledochal cyst, and the Kasai hepatoportoenterostomy procedure for biliary atresia as well as other procedures potentially affecting the biliary tree. With the understanding that these are relatively rare procedures, case reports and small case series are included in addition to larger series when available. The review focuses on publications in English over the past 15 years...

In the Western world, liver abscesses are predominantly of pyogenic origin and can present a wide range of ultrasonographic features, from a solid mass to a cystic cavity. Amoebic abscesses are endemic in tropical areas and typically round single lesions. Echinococcal cyst is diagnosed by ultrasound (US). Serology is particularly useful when pathognomonic US features are absent. Treatment is determined based on the WHO ultrasonographic classification, and puncture, aspiration, injection, re-aspiration (PAIR) is a US-guided therapeutic option...

BACKGROUND: Choledochal cysts are associated with ductal strictures, stone formation, cholangitis, rupture, secondary biliary cirrhosis and increased incidence of cholangiocarcinoma. The surgical approach to choledochal cysts has evolved from the cyst-enterostomy to a complete excision with more recent use of minimally invasive approaches. We report a complete minimally invasive approach to a Type 1 choledochal cyst and summarize the literature containing large case series of similar approaches...

Most cystic lesions of the liver are found incidentally in imaging studies because they are not symptomatic, and generally do not require treatment. Rarely, however, symptomatic hepatic cysts may develop complications and require treatment. Here, we describe a case of a 77-year-old woman who developed biliary obstruction with abdominal pain due to compression of the bile duct by a simple hepatic cyst. We confirmed the diagnosis based on symptoms and imaging studies. The patient'ssymptoms improved after simple cyst ablation by sclerotherapy...

Choledochal cysts involving the cystic duct are extremely rare, and are usually associated with cystic dilatations of the extrahepatic biliary tract. We describe a patient who presented with jaundice and was found to have a dilatation of the common bile duct on computed tomographic imaging, consistent with a choledochal cyst. He underwent a laparoscopic-converted-to-open cholecystectomy with excision of the choledochal cyst which was found to involve the cystic duct. Choledochal cysts involving the cystic duct are notably missing from the Todani classification...

BACKGROUND & AIMS: Genetic defects in polycystin-1 or -2 (PC1 or PC2) cause polycystic liver disease associated with autosomal dominant polycystic kidney disease (PLD-ADPKD). Progressive cyst growth is sustained by a cAMP-dependent Ras/ERK/HIFα pathway, leading to increased vascular endothelial growth factor A (VEGF-A) signaling. In PC2-defective cholangiocytes, cAMP production in response to [Ca(2+)]ER depletion is increased, while store-operated Ca(2+) entry (SOCE), intracellular and endoplasmic reticulum [Ca(2+)]ER levels are reduced...

: Choledochal cyst is a rare pathological condition, which represents 1% of benign diseases of the biliary tract. It is seen with significant frequency in childhood, with a higher prevalence in females, and a greater diagnostic incidence in Asia. Diagnosis is primarily based on clinical suspicion. Its symptoms are variable, and its treatment, depending on the type, is surgical. CASE REPORT: a male patient, 46 years old, with clinical symptoms of acute pancreatitis as a complication of a choledochal cyst Todani type II is diagnosed during his hospital stay with cholangial magnetic resonance...

BACKGROUND: Choledochal cyst is a congenital dilatation of the biliary tree. It may affect only the extrahepatic bile duct (type I, II and III), intrahepatic (type V) or both (type IVa). Vater first described choledochal cyst in 1723. Open excision was the standard procedure made a great impact in the treatment but since 1995 Farello et al. first reported laparoscopic choledochal cyst excision and this has been used worldwide. CASE REPORT: Female, 17 years old, past medical history two years ago a laparoscopic cholecystectomy for gallbladders...

Introduction. Gallbladder volvulus is a rare, potentially fatal condition unless diagnosed and treated early. Choledochal cysts are rare congenital malformations of the biliary tree predisposing to different pathologies and posing the risk of degradation into cholangiocarcinoma and gallbladder cancer. Dealing with both diseases at once has not been published yet in the literature. Presentation of Case. We report a case of gallbladder volvulus in an elderly female who happened to have a concomitant type I choledochal cyst...

Unlike its family member p53, TP63 is rarely mutated in human cancer. However, ΔNp63α protein levels are often elevated in tumors of epithelial origin, such as squamous cell carcinoma and cholangiocarcinoma. To study the oncogenic properties of ΔNp63α in vivo, we generated transgenic mice overexpressing ΔNp63α from the Rosa26 locus promoter controlled by keratin 5-Cre. We found that these mice spontaneously develop epidermal cysts and ectopic ΔNp63α expression in the bile duct epithelium that leads to dilatation of the intrahepatic biliary ducts, to hepatic cyst formation and bile duct adenoma...
